VA-One

VA One : The ONE simulation environment for vibro-acoustic analysis and design

VA One is a complete solution for simulating the response of vibro
-acoustic systems across the full frequency range. VA One seamlessly
combines Finite Elements (FE), Boundary Elements (BEM) and
Statistical Energy Analysis (SEA) in ONE model. It is
the only simulation code on the market today that contains the complete
spectrum of vibro-acoustic analysis methods within ONE common environment.

Structural FE Module

The Structural Finite Element (FE) Module of VA One contains
all the
functionality you need to create and work with Finite Element
structural subsystems within the VA One environment.

Create and solve for the response of structural FE subsystems entirely within
VA One using the inbuilt Nastran solver and/or import existing
models and results from a large variety of external FE solvers.

Acoustic FE Module

The Acoustic Finite Element (FE) Module gives you all the
functionality you need to add fully coupled FE acoustic cavity subsystems to
your VA One models.

It is ideally suited for creating accurate models of enclosed acoustic cavities
at low frequencies and for optimizing the low frequency performance of poroelastic
noise control treatments.

Acoustic BEM Module

The Acoustic Boundary Element Module contains all the functionality you need to
model the low frequency response of bounded and unbounded fluids within the
VA One environment (including Fast Multipole Boundary Elements for solving large models).

The module is the evolution of the RAYON Boundary Element solver and
enables you to create accurate models of fluid loading, scattering,
radiation and transmission of sound at low frequencies.

Hybrid Module

The Hybrid Module gives you the
state-of-the-art in vibro-acoustic analysis methods.

Developed as part of a long term research program by ESI,
in conjunction with leading academic institutions and industrial consortia, this module
enables you to create fully coupled FE/BEM/SEA models
in a single analysis. The ultimate in modeling flexibility; use
the right combination of subsystems to accurately model the response of your
product across the entire frequency spectrum.

SEA Module

The Statistical Energy Analysis (SEA) module of VA One is
the evolution of the industry standard software for mid and high-
frequency noise and vibration design, AutoSEA2. The SEA module is
used routinely in virtually every industry for which noise and vibration are
of concern. Find out why so many companies have made ESI
ssoftware a standard part of their noise and vibration design process.

Foam Module

The Foam module expands VA One's library of materials to
include advanced poroelastic materials based on full Biot theory. At low
frequencies, this enables you to add "foam finite element"
(PEM) subsystems to your existing VA One models and couple
them to adjacent FE structure and FE acoustic subsystems. At mid
and high frequencies, this enables you to integrate more advanced noise
control treatment layups into your existing SEA and Hybrid models. Using
the Foam module you can ensure optimal use of foams and fibers in your applications.
